Doing..and undoing..

I write and erase,
And again I write.
I walk and fall,
And again walk upright.
I hope and lose,
And again I hope.
I smile and cry,
And again start smiling.
I live in circles,
I hate the squares,
I indulge in repetition,
For all I care.
I love life and hate,
I again start to love.
With my actions and words,
I lit fire by the stove.
